Antarctic Peninsula melt season durations based on level 1 ASCAT scatterometer data, 2017-2020

Three datasets of melt season duration in days covering the Antarctic Peninsula for the austral yeas of 2017/2018, 2018/2019 and 2019/2020. The datasets are based on ASCAT GDS Level 1 Sigma0 Swath Grid data from the EUMETSAT archive (archive.eumetsat.int/usc/) and extend an earlier time series based on enhanced QuikSCAT and ASCAT data (doi:10.5285/e3616d28-759e-4cca-8fae-fe398f9552ba). The data are supplied as GeoTIFFs.

Funding was provided from the NERC grant NE/L005409/1.

Statement: Scatterometer data were missing between 12/12/2017 and 02/01/2018, and between 17/12/2018 and 15/01/2019. The data for 2019/2020 only go to 17/04/2020. Therefore there is the possibility that melt durations are underestimated. However, the affect of the 2017, 2018 and 2019 missing data is minimal as most melt takes place later in the summer.
